*A commercially bagged potting mix is not exactly environmentally friendly. They can contain synthetic fertilisers which require lots of energy to create, can also contain sand mined from natural ecosystems, and may also have travelled long distances. For example, I broke all the rules buying the above bag of potting mix. It contains washed sand, slow-release fertiliser, and travelled interstate hundreds of kilometres. To reduce the ecological impact of bagged potting mix, look for locally made organic compost made from recycled materials. For example, some councils sell bagged compost made from composted green waste.
